## URI Request Parameters
<a name="API_CreateAccessor_RequestParameters"></a>

The request does not use any URI parameters.

## Request Body
<a name="API_CreateAccessor_RequestBody"></a>

The request accepts the following data in JSON format.

 ** [AccessorType](#API_CreateAccessor_RequestSyntax) **   <a name="ManagedBlockchain-CreateAccessor-request-AccessorType"></a>
The type of accessor.  
Currently, accessor type is restricted to `BILLING_TOKEN`.
Type: String  
Valid Values: `BILLING_TOKEN`   
Required: Yes

 ** [ClientRequestToken](#API_CreateAccessor_RequestSyntax) **   <a name="ManagedBlockchain-CreateAccessor-request-ClientRequestToken"></a>
This is a unique, case-sensitive identifier that you provide to ensure the idempotency of the operation. An idempotent operation completes no more than once. This identifier is required only if you make a service request directly using an HTTP client. It is generated automatically if you use an AWS SDK or the AWS AWS CLI.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Required: Yes

 ** [NetworkType](#API_CreateAccessor_RequestSyntax) **   <a name="ManagedBlockchain-CreateAccessor-request-NetworkType"></a>
The blockchain network that the `Accessor` token is created for.  
+ Use the actual `networkType` value for the blockchain network that you are creating the `Accessor` token for.
+ With the shut down of the *Ethereum Goerli* and *Polygon Mumbai Testnet* networks the following `networkType` values are no longer available for selection and use.
  +  `ETHEREUM_MAINNET_AND_GOERLI` 
  +  `ETHEREUM_GOERLI` 
  +  `POLYGON_MUMBAI` 

  However, your existing `Accessor` tokens with these `networkType` values will remain unchanged.
Type: String  
Valid Values: `ETHEREUM_GOERLI | ETHEREUM_MAINNET | ETHEREUM_MAINNET_AND_GOERLI | POLYGON_MAINNET | POLYGON_MUMBAI`   
Required: No

 ** [Tags](#API_CreateAccessor_RequestSyntax) **   <a name="ManagedBlockchain-CreateAccessor-request-Tags"></a>
Tags to assign to the Accessor.  
 Each tag consists of a key and an optional value. You can specify multiple key-value pairs in a single request with an overall maximum of 50 tags allowed per resource.  
For more information about tags, see [Tagging Resources](https://docs.aws.amazon.com/managed-blockchain/latest/ethereum-dev/tagging-resources.html) in the *Amazon Managed Blockchain Ethereum Developer Guide*, or [Tagging Resources](https://docs.aws.amazon.com/managed-blockchain/latest/hyperledger-fabric-dev/tagging-resources.html) in the *Amazon Managed Blockchain Hyperledger Fabric Developer Guide*.
